The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

The embodiment of the utility model provides a multilayer transmission device 10 and a transmission robot, which are used for solving the problem of lower production efficiency caused by manual feeding and discharging in the prior art.

In an embodiment of the present utility model, please refer to fig. 1, the transfer robot includes a multi-layer transfer device 10 and a conveying device 20, wherein the conveying device 20 is connected to the multi-layer transfer device 10 for driving the multi-layer transfer device 10 to move. The transport device 20 may be configured as a hidden robot, or other device with automated transport, and may be configured in a manner that is more conventional in the art, and will not be described herein.

Referring to fig. 2, the multi-layered conveyor 10 includes a frame 11, a driving assembly 13, a bin 30, and a plurality of conveying rails 12; each conveying track 12 is arranged on the frame 11 at intervals along a first direction, each conveying track 12 comprises a plurality of rotating rollers 121 which are arranged along a second direction, the first direction is perpendicular to the second direction, each rotating roller is movably connected with the frame 11, and the storage bin 30 is movably connected with the conveying track 12; the transmission assembly 13 is disposed on the frame 11, and the transmission assembly 13 is used for driving each rotating roller 121 to rotate so as to drive the bin 30 to move along the second direction.

Since the multilayer conveying device 10 needs to have a function of feeding materials into a production line and a function of recovering processed materials from the production line, in the present utility model, the main application form of the multilayer conveying apparatus is to provide two layers of conveying rails 12, corresponding to input and output of materials, respectively, so that the description and drawings are directed to the case of providing two layers of conveying rails 12, and the multilayer conveying device 10 having other layers only needs to repeatedly increase the conveying rails 12 and the transmission assemblies 13 related thereto, and the description will not be given for the case of more than two layers.

Taking the case that the lower layer of conveying track 12 is responsible for feeding (the bin 30 is sent into the production line) and the upper layer of conveying track 12 is responsible for receiving (the bin 30 is recovered from the production line) as an example, the working process of the conveying robot is as follows: the conveying device 20 drives the multilayer conveying device 10 and the bin 30 thereon to reach the production line, the bin 30 is loaded with a PCB board for processing, after the conveying device 20 is in place, the production line is in butt joint with the conveying rail 12 at the lower layer, the transmission assembly 13 drives the rotating roller 121 to rotate, the bin 30 moves into a conveying belt on the production line, the manipulator takes away the PCB for processing, after the processing is completed, the PCB is put back into the bin 30 by the manipulator, the conveying belt is in butt joint with the conveying rail 12 at the upper layer and conveys the bin 30 to the conveying rail 12 at the upper layer, and the transmission assembly 13 drives the rotating roller 121 to rotate so as to recycle the bin 30.

In the above process, the butt joint of the conveyor belt and the different conveying rails 12 can be realized in two forms, one is to provide two conveyor belts, each conveyor belt is in butt joint with one conveying rail 12, and a lifting assembly can be also arranged below the conveyor belt, and the conveyor belt is driven to lift by the lifting assembly to be in butt joint with the different conveying rails 12.

The direction in which the transmission assembly 13 can drive the rotating roller 121 to rotate may be unidirectional or bidirectional. When the transmission direction is unidirectional, one conveying track 12 is fixedly responsible for feeding, and the other conveying track 12 is fixedly responsible for discharging; when the direction of transmission is bi-directional, the function of the two conveyor tracks 12 can be switched conveniently, thereby providing greater flexibility.

The multilayer transmission device 10 adopts the transmission component 13 to drive the rotating roller 121 to rotate, and the rotating roller 121 drives the bin 30 to move along the conveying track 12, so that the bin 30 is sent into a production line, or the bin 30 is recovered from the production line, the process of manually conveying the bin 30 is omitted, and the labor intensity of workers is reduced; the conveying robot adopts the conveying device 20 to drive the multilayer conveying device 10 to move between different production lines, the conveying device 20 can walk according to a preset route, and compared with manual conveying, the conveying robot greatly reduces the conveying error rate. Overall, this transmission robot has improved the efficiency of going up unloading and transporting in the PCB production link to production efficiency has been improved.

In one embodiment, the multi-layer transmission device 10 further includes a sensing assembly and a control assembly, the sensing assembly includes a plurality of sensors disposed on the frame 11, the sensors are used for detecting the position information of the storage bin 30, and the control assembly is used for controlling the rotation or stop of the transmission assembly 13 according to the position information detected by the sensing assembly. In this embodiment, the particular type of sensor may be selected from existing position sensors, such as electromagnetic, photoelectric or hall type position sensors.

The provision of the sensing assembly 13 and the control assembly has the advantage that the transmission assembly 13 can be started or stopped in dependence on the positional information provided by the sensing assembly, thereby enabling automated control.

For simplicity of description, the following description will refer to an opposite sensor in which the sensor is preferably an optoelectronic sensor, and generally, the opposite sensor includes a transmitter for emitting an optical signal and a receiver for receiving the optical signal, where the transmitter is disposed on one side of the conveying track 12, and the receiver is disposed on the other side of the conveying track 12.

In a specific embodiment, the sensor comprises a first sensor 141, the first sensor 141 being connected to the frame 11 and being located at the end of the conveyor track 12 close to the production line.

Specifically, as shown in fig. 9, when the bin 30 is at the predetermined position, the optical signals of the first sensor 141 and the second sensor 142 are not blocked, however, due to the error of the driving assembly 13 during driving and the inertia of the bin 30, the bin 30 tends to overshoot left (as shown in fig. 10) or overshoot right (as shown in fig. 11) when the driving assembly 13 is stopped, and at this time, the optical signals of the first sensor 141 or the second sensor 142 are blocked to send out signals, and the driving assembly 13 rotates forward or backward, so that the bin 30 is brought back to the predetermined position.

In a more specific embodiment, the sensor further comprises a third sensor 143 located between the first sensor 141 and the second sensor 142.

The purpose of the third sensor 143 is to determine whether the bin 30 is positioned in the conveyor track 12 based on whether the light signal from the third sensor 143 is blocked when the device is suddenly de-energized and restarted.
